There were over 10,000 people who work in tech who completed the survey, Nazar said.

We don't know how many of those are from Austin, but CEO Jason Nazar said it was a statistically significant sample of "at least a couple hundred" Austin residents.

Nazar said the survey respondents definitely skewed heavily male. There were 2.5 men for every one woman who completed the survey.

I'm willing to guess that one reason for the gender pay gap in tech in Austin, and in general, is that men tend to dominate some of the higher-paying fields, such as software programmer. And women tend to be over-represented in lower-paid jobs areas in areas like marketing and customer support.

Comparably has some other interesting infographics on their wage gap data. This chart breaks it down by age. Interestingly, women early in their careers had the biggest pay gap.

This chart is also interesting. It shows the wage gap by department. Finance and Marketing don't fare well, with wage gaps of over 25 percent.

Women do well in two very interesting categories: lower-wage administrative jobs and highly-paid executive positions. Just a guess, but executive salaries often are public, especially if the company is publicly-traded. This may help women's salaries be more on par with men.
